You know, imagine SS dies here. I can say this volume will be the volume that changed fans forever. Well not in general, but I won't be surprised if US sales is lower than before after the release.
I am from the US and I am a NS fan. IMO, Sakura status will improve when she is finally over Sasuke. I still believe that is where a lot of the hate comes from.
I think the fans that care about the pairs will leave for a little bit, but come back for the ending. I want to see if Naruto is the next SO6Ps.
I hope Kishi ends SS soon. I feel if he keeps the ship wars alive, he is bringing hatred against his characters. Plus I can't grasp Sakura still being in love with Sasuke after everything too. When Sasuke shows his true motive, I can't see her still struggling with her feelings after that.
IMO, it would be best to end SS in the next chapter. Then let NS grow from there.
